7 0

Answer:

f(x) = 6 x^2 - 1

f(2) = 6 * 2^2 - 1 = 23

f(-1) = 6 * -1^2 - 1 = 6 * 1 - 1 = 5

f(2) - f(-1) = 23 - 5 = 18

YM is a median of the triangle below. XM = 2x + 2 and ZM = 4x - 8. What 5 points
LenaWriter [7]

Answer:

Option A: 12

Step-by-step explanation:

From the image of the triangle given, we can see that:

XM = ZM

We are given that:

XM = 2x + 2 and ZM = 4x - 8

Thus;

2x + 2 = 4x - 8

Rearrange to get;

4x - 2x = 8 + 2

2x = 10

x = 10/2

x = 5

Thus, XM = 2(5) + 2

XM = 12

The first question is 50% because a total of 30 girls bought lunches out of 60 kids

the second question, the easiest way is to plug in the x and y coordinates
3(4) - 2(0) = 12
12-0=12
12=12
because 12 = 12 is true, the first pair is the answer
